Re: grub hangs after update



I saw the same thing about a week ago.  The problem was the master boot
record (MBR).  This is how I fixed it (note that I backed everything up
one more time before doing this).  

<disclaimer>Please note that this rebuilds the MBR so it's not to be
tried without understanding what you're doing</disclaimer>

1.  Boot from a rescue disk to "repair" the system.
2.  Let the start-up process find and mount your filesystem.
3.  Chroot to /mnt/sysimage
4.  Look at /etc/grub.conf to both be sure it looked OK and to
    look for the "root (hd0,0)" or "root (hd0,1)" or whatever line.
5.  Run "grub"
    5a.  type in "root (hd0,0)", which is what I found in grub.conf
    5b.  type "setup (hd0)"
6.  Rebooted the system and it all started up.

Take a look at the page:
